Processing Technology of Azalea Flowers

Abstract

Azalea absolute oil is used in the highest quality perfumery liquids production, although because of muddying of perfumery product during the storage process and sediment separation, its wide usage was hold up. In spite of fact that Azalea absolute oil production started long time ago the influence of absolute oil receiving technology regime’s separate factors on the absolute oil productivity and quality was not investigated. The technological regime of receiving absolute oil from Azalea concrete was investigated in details. As a result it was established that concrete should be processed with 96% ethyl alcohol (solute) during 6 hours, the subsequent waxes – during 4 hours, and the alcoholic solutions obtained during the processing of concrete and waxes should be kept for 2 hours at minus 12-150C. It is necessary to coupage and concentrate the alcohol solutions obtained during the processing of concrete and waxes to 10% absolute oil content and delay for 20 days and nights. After a delay, the concentrated solution should be filtered and the solvent transferred. The established technological regime lets an absolute oil to be free from sediment (triterpene alcohols), their existence in perfumery liquids caused muddying and separation of amorphous sediments.
